Dame Stella Rimington has been given the go-ahead to become the first British spymaster to release a book about their experiences.

The former head of MI5's book, Open Secret, will be published in September.

The decision was reportedly taken by the Prime Minister, Tony Blair,
the Home Secretary, David Blunkett, and the Foreign Secretary, Jack Straw, and relayed to Dame
Stella by her successor, Sir Stephen Lander.

Ministers dropped their opposition to publication after she agreed to scrap a number of passages, and change others, on
the grounds of national security, according to the Home Office.

There is not now any justification for the government resisting publication of the book, so we are not

A spokeswoman said: "The government regrets and disapproves of the decision to publish a book - but that is not the same as resisting it.

"There is not now any justification for the government resisting publication
of the book, so we are not."

Dame Stella, the first head of the secret service to be officially named and photographed, has faced strong opposition throughout Whitehall.

She is said to have been opposed by Sir
Stephen and the head of MI6, Sir Richard Dearlove, while the former Chief of Defence Staff, General Sir Charles Guthrie, strongly
criticised her attempt to publish.

But, after the 65-year-old reportedly threatened to invoke her right to freedom of
expression under the Human Rights Act, ministers and officials are said to have
concluded that they could not block publication.
